Hi R-users:

I've got a problem with lme.

In Rail data,I try to model the next one

lme(travel ~ Rail, data = Rail, random = ~ Rail | Rail)

I want travel = Rail(i) + Rail(j) + epsilon(i,j)

say, an effect fixed for every Rail and other for Rail(j) random, R says
fewer observations or false convergence.

Why can't I model an effect fixed and other random?

Thanks in advance.
